Kev kuaj ultrasonic siv ntau tus yam ntxwv ntawm ultrasound los txiav txim seb puas muaj qhov tsis xws luag hauv cov khoom kuaj lossis cov khoom siv los ntawm kev soj ntsuam cov kev hloov pauv ntawm ultrasound hauv cov khoom kuaj lossis cov khoom ua haujlwm tso tawm ntawm lub ntsuas ntsuas ultrasonic.
Kev nthuav tawm thiab kev hloov pauv ntawm ultrasound hauv cov khoom kuaj lossis cov khoom ua haujlwm muaj cov ntaub ntawv nplua nuj, uas tuaj yeem pab peb kom tau txais cov ntaub ntawv ntxaws txog cov qauv sab hauv. Los ntawm kev ntsuam xyuas ultrasonic, peb tuaj yeem kuaj xyuas ntau yam tsis xws luag, xws li cov kab nrib pleb, corrosion, pores, thiab kev suav nrog. Cov kev tsis zoo no yuav muaj kev cuam tshuam loj rau lub zog, kev ntseeg siab, thiab kev nyab xeeb ntawm cov ntaub ntawv, yog li kev kuaj ultrasonic yog qhov tseem ceeb hauv kev tsim khoom thiab kev lag luam.
Lub hauv paus ntsiab lus ntawm kev kuaj ultrasonic yog nyob ntawm qhov sib txawv ntawm qhov kev nthuav tawm ceev ntawm ultrasonic tsis nyob rau hauv cov ntaub ntawv sib txawv. Thaum ultrasonic nthwv dej ntsib qhov cuam tshuam los yog qhov tsis xws ntawm cov ntaub ntawv, lawv yuav xav txog, thim rov qab, lossis tawg. Cov teeb liab no tau txais los ntawm cov sensors thiab hloov mus rau hauv dluab lossis waveforms rau tso saib los ntawm kev ntsuas ultrasonic. Los ntawm kev txheeb xyuas qhov tsis xws li amplitude, ncua sij hawm, thiab morphology ntawm ultrasonic signals, peb tuaj yeem txiav txim siab qhov chaw, qhov loj me, thiab cov khoom ntawm qhov tsis xws luag.
Ultrasonic kuaj muaj ntau yam zoo, ua rau nws siv dav siv txoj kev kuaj. Ua ntej, nws yog cov cuab yeej tsis sib cuag uas yuav tsis ua rau muaj kev puas tsuaj rau cov khoom siv los yog cov khoom ua haujlwm. Qhov no ua rau lub sijhawm saib xyuas kev kuaj ultrasonic ntawm cov kab ntau lawm, txhim kho kev tsim khoom thiab cov khoom zoo. Qhov thib ob, ultrasound tuaj yeem nkag mus rau cov khoom siv feem ntau, suav nrog hlau, yas, ceramics, thiab cov khoom sib xyaw. Qhov no ua rau kev kuaj ultrasonic haum rau qhov kev xav tau ntawm ntau yam ntaub ntawv thiab cov qauv.
Tsis tas li ntawd, kev kuaj ultrasound tseem tuaj yeem muab cov ntaub ntawv ntau. Los ntawm kev ntsuas qhov kev nthuav tawm ceev thiab amplitude hloov ntawm ultrasonic tsis, peb tuaj yeem xam qhov loj thiab qhov tob ntawm qhov tsis xws luag. Qhov peev xwm no tseem ceeb heev rau kev ntsuas kev ncaj ncees thiab kev ntseeg siab ntawm cov qauv. Rau qee qhov kev siv tshwj xeeb, xws li kev tshawb nrhiav cov raj xa dej, ntim, thiab cov qauv dav hlau, kev kuaj ultrasonic kuj tau siv dav.
Txawm li cas los xij, kuj tseem muaj qee qhov kev sib tw thiab kev txwv hauv kev kuaj ultrasonic. Ua ntej, kev nthuav tawm ntawm ultrasound yog cuam tshuam los ntawm yam xws li cov khoom nqus, tawg, thiab diffraction. Qhov no tuaj yeem ua rau txo qis ntawm lub zog ntawm lub teeb liab thiab distortion ntawm cov duab, yog li txo qhov tseeb ntawm kev tshawb pom. Qhov thib ob, kev nthuav tawm ceev ntawm ultrasound hauv cov ntaub ntawv tseem cuam tshuam los ntawm cov yam ntxwv xws li kub, av noo, thiab kev hloov pauv ntawm cov khoom siv. Yog li ntawd, thaum tsim thiab ua tiav kev soj ntsuam ultrasonic, nws yog ib qho tsim nyog yuav tau xav txog cov yam ntxwv no thiab ua calibration thiab kho.
Hauv cov ntsiab lus, kev ntsuam xyuas ultrasonic yog ib qho kev txhim khu kev qha, hloov tau, thiab siv dav siv tsis yog kev ntsuas kev puas tsuaj. Los ntawm kev soj ntsuam kev nthuav tawm thiab kev hloov pauv ntawm ultrasonic tsis nyob rau hauv cov khoom siv kuaj lossis cov khoom ua haujlwm, peb tuaj yeem txiav txim siab seb puas muaj cov teeb meem sab hauv. Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, kev sim ultrasonic yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, muab peb cov qauv tsim muaj tseeb thiab txhim khu kev qha.
